name-parser: Fill short and long name as TypoFamily

[why]
This sets out to circumvent a problem with VisualStudio 2022. That
application seems to have problems with fonts when the ID16 is not a
prefix in ID1.

We have this when --makegroups >= 4, because

ID1  has the short name suffix 'NF'
ID16 has the long suffix 'Nerd Font'

These fonts can be selected in VisualStudio 2022, and the preview works
ok, but once active some replacement default font is used instead.

The problem vanishes if ID16 and ID1 have the same stem, or rather ID1
has someting added on top of ID16; but ID16 is a substring of ID1.

See more discussions in #1442

[how]
Write both forms in ID16 fields, 'NF' and 'Nerd Font' suffixes. This
works as long as the application considers all languages equal.
